T 0 (ZZZ whom it may concern:

Be it known that I, EARLE E. CHAPMAN, acitizen of the United States,residing at Los Angeles, Los Angeles County, California, have invented anew and useful Improvement Comprising the Shackle for Automobile Viiheels and Spokes, of which the following is a specification.

My invention relates to shackles which are adapted to be secured aboutthe wheel of an automobile for the purpose of preventing theft orunauthorized use thereof. Such shackles are ordinarily secured about oneof the front wheels, being locked therearound so that the shackle isdifficult to remove and so that they will produce an unmistakable soundand make a plain trail in case the automobile is operated with theshackle in place thereon.

An object of the invention is to provide a shackle for this purposewhich will make an unmistakable sound, preventing the automobile fromrunning at a high speed, and which will also leave a distinctive mark onthe surface of the street in case the automobile is driven with theshackle in the place on the wheel thereof. For this purpose I provide abumping member which is secured on the tread of a tire and provided witha sharp projection so placed as to dig into the street it the automobileis moved with the shackle in place.

A further object of the invention is to provide a device which inaddition to looking about the tire and felly of the wheel, will alsolook about a spoke so that the shackle cannot be turned around on thetire to put the projection or bumping member out of action.

Further objects and advantages will be made evident hereinafter.

Referring to the drawing which is for illustrative purposes only, Fig. 1is a, view of the Wheel of an automob'le with a shackle in placethereon.

Fig. 2 shows a shackle using a one piece locking clamp.

Fig. 3 shows a clamp.

All of these forms of shackle are designed to go over a tire 11, carriedon a wheel 12 having a felly 13 and a series of spokes 14. Each of theshackles illustrated comprises a bumping block having a perspective viewof this pointed projection 21 which is so shaped that it will make adistinctive mark on the street in case the automobile is run with theshackle in place as shown in Fig. 1.

Extending upwardly from one side of the bumping block 20 is an arm 22which terminates in a projection 23 which extends inside the felly 13 ofthe wheel when the shackle is in place thereon.

An arm 24 pivotedon a pin 15 on the bumping block 20 extends up and hasprojection 25 carrying a lock 26, the lock 26 locking the projections 28and 25 together when the shackle is in place on the wheel. Projections23 and 25 are preferably cylindrical. v

It will be noted that the shackle can turn from the full line positionshown in Fig. 1 to either of the dotted positions shown in that figurewithout exerting any wedging or jamming action on the spoke.

For the purpose of looking around the spoke I provide an attachment 3Ocomprising a bent piece of metal having holes 31 therein of proper sizeto allow the projections 23 and 25 to pass tlierethrough. The signal maybe used with or without the attachment 30. When the attachment is used,it insures the signal being held in place in case the tire 11 ispurposely or accidentally deflated, thus giving some slight additional'security.

This application is a division of my application Serial No. 863,087,filed March 2, 1920.

I claim as my invention:

1. A shackle for an automobile wheel comprising a bumping block; armsfor securing said block upon the tread of said wheel; projections onsaid arms meeting inside the folly of the wheel; means for locking saidprojections together; and a U-shaped member of proper size to encircle aspoke, said U-shaped member having holes in either limb through whichsaid projections pass and lock.

2. A shackle for an automobile wheel comprising a bumping block; aprojection formed on said block and adapted to make a distinctive markon the surface of the street if the automobile is moved with the shacklein place on a wheel thereof, arms for securing said block upon the treadof said wheel; projections on said arms meeting in side the folly of thewheel; means for locking said projections together; and a U-shapedmember of proper size to encircle a spoke, said U-shaped member havingholes in either limb through which said projections pass and lock.

3. In combination, a theft preventing device adapted to be applied tothe tire and rim of an automobile wheel comprising a member adapted toproject radially from the tread of the tire, relatively movable armsextending inwardly from said member on opposite sides of the tire andrim, coupling parts carried by the inner ends of said arms and adaptedto be brought together at the inner side of said rim, a locking meansfor releasably locking said coupling parts together, of a yoke removablyengaged with said parts and adapted to embrace a spoke of the wheel toprevent the device from being turned upon the tire and rim whereby tomaintain said member at the tread of the tire.

4:- In combination, a theft preventing device adapted to be applied tothe tire and rim of an automobile wheel comprising a member adapted toproject radially from the tread of the tire, relatively movable armsextending inwardly from said member on opposite sides of the tire andrim, coupling parts carried by the inner ends of said arms and adaptedto be brought together at the inner side of said rim, a locking meansfor releasably locking said coupling parts together, of a yoke havingopenings to receive the coupling parts and adapted to embrace a spoke ofthe wheel to prevent the device from being turned upon the tire and rimwhereby to maintain said member at the tread of the tire.

5. A shackle for an automobile wheel com prising a bumping block; aprojection formed on said block and adapted to make a distinctive markon the surface of the street if the automobile is moved with the shacklein place on a wheel thereof; arms for securing said block upon the treadof said wheel; projections on said arms meeting inside the telly of thewheel; means for locking said projections together; and means pivoted onsaid projections for encircling a spoke of said wheel.

In testimony whereof, I have hereunto set my hand at Los Angeles,California, this 15th day of February 1921.

EARLE E. CHAPMAN.
